FEEDING MECHANISM FOR THRESHINGeMACHINES.

To all whom it may concern:

Be it known that I, FnEDnRIoo I'IANSEN, a citizen of the United States,residing at Buenos Aires, Argentina, have invented certain new anduseful Improvements in Feeding Mechanism for Threshing-Machines, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to feeders for threshing machines, and has forits object to produce an attachment of this character possessing novelfeatures of construction and arrangement and adapted to deliver thestraw to be threshed from relatively long ricks or stacks.

In the accompanying drawingsFigure 1 is a plan view of a portion of athreshing machine, and of a feeder embodying my invention securedthereto. Fig. 2 is a side elevation, and Fig. 3 is a rear elevation ofthe parts represented in Fig. 1. Fig. 4 is a longitudinal sectional viewof the laterally extending adjustable straw carrier. Fig. 5 is a detailView of one of the supporting devices for the inner end of thetransverse conveyer frame. Fig. 6 is a detail view of one of themountings for the winding shaft. Fig. 7 is a detail view of one of themedial supporting devices for the lower run of the transverse conveyeraprons.

In the drawings, A represents the rear portion of a threshing machine,which may be of any usual or preferred construction.

B represents that part of the casing which incloses the cylinder andconcave, the former being mounted upon the shaft 0. This shaft isprovided with a pulley f around which passes the main driving belt, andwith other pulleys d, e and 9. Around the pulley 03 passes the belt Dthat drives the fan, and the belt E that drives the beater, and thepitman shaft engages with the pulley e. A belt H engaging with thepulley 9 drives the band cutting devices, the pulley h of which isshown. The band cutters and devices for feeding the straw after thebands are severed is inclosed by the portion J of the casing. A pulley zis mounted on the shaft I of the band cutter, and is connected by thebelt or band K with a pulley 70, mounted upon a transversely arrangedshaft 24 suitably mounted in the upper part of the thresher frame workor casing. In rear of the portion of the casing in which areSpecification of Letters Patent.

mounted the band cutters is situated a longitudinally arranged conveyeror carrier L provided with an endless apron or belt Z adapted to receivethe straw and convey it toward the band cutters and feeders.

The parts thus far described, may be of any usual or preferredconstruction.

The rearward extending longitudinally disposed conveyer carries a frameadapted to support the inner end of a laterally arranged carrier 0. Thisframe comprises a rear cross bar 2, uprights 33 rising therefrom, andfront uprights 4 secured to and rising from the sides of the frame ofthe carrier L. Inclined supporting bars 55 are secured to the upper endsof the uprights 3 and 4 and are secured together at their up per ends bythe metallic connecting pieces 6. The latter are constructed to formhearings in which is mounted a rotatable shaft 7 The laterally extendingcarrier or con veyer O is formed of two sections pivotallyconnected,--an inner section 8 and an outer section 9. In the frame thusformed there is mounted an endless apron or belt 10 adapted to travelaround the supporting rolls 11 and 12, the former being located at theinner end of the inner section of the carrier frame, and the latter atthe outer end of the outer section. In order to prevent the lower run orleg of the endless belt from sagging unduly, I provide the side bearings14 of the inner section of the conveyer with inwardly extending pins orrods 13 over which pass the edge portions of the apron or belt, thesepins being preferably arranged as indicated in Fig. 7 and carryinganti-friction sleeves or rollers.

The inner end of the laterally extending conveyer O is detachablysupported by the rearward longitudinal conveyer L which is provided witha pair of recessed lugs or hooks 39 adapted -to receive pivot pins orshaft 38 carried by the conveyor 0. The hooks 39 are open as clearlyrepresented in Fig. 3 so that it is easy to drop the pins or ends of theshaft 38 thereinto and thus connect the two carriers. The outer end ofthe carrier 0 is sustained in a suspended position by ropes or cords1:"), the inner ends of which are wound upon the shaft 7. The cords areconnected at their outer ends to the outer section 9 of the conveyer andare supported intermediate between their ends by frames 16 situated nearthe inner ends of the outer section, which serve to hold the cords in anelevated position, or radially distant from the axis 36 of the hingesthat unite the two sections 8 and 9. To the end of the shaft 7 there issecured a wheel 17, connected, by a sprocket chain or band 18, with apinion 20 mounted on a short shaft, that is preferably supported in thecross bar 2 of the frame work, and is provided with a crank handle 19.By turning this handle the shaft 7 isrotated and the cords 15 let off orwound upon the shaft 7 to adjust the position of the laterally extendingconveyer. The curve followed by the outer portion of the conveyer as itis adjustedup or down when fully extended, is indicated by the dottedline 00 in Fig. 3. In this figure I have represented how the lateralcarrier may be folded up over the longitudinal conveyer, as when it isdesired to transport or store the apparatus.

The position of the parts indicated in dotted lines at I is that assumedby them at the first stage of the folding operations. Starting with theparts in the position represented in full lines, the attendant liftsupon the carrier, applying pressure at about the line 36 where the twosections join or are pivoted together. This causes the sections as awhole to buckle, the inner section 8 rising about the .pivot 38, whilethe outer section moves downwarduntil it assumes substantially avertical position. If, now, the cords be wound upon the shaft 7 the artsmay be brought first to the position indicated in dotted lines at II,and later to that represented at II'I. When in this last position thefree end of the outer section is drawn in toward the lower side of theinner section, and the latter rests against the shaft 7, the parts thusbeing brought .into compact relations with each other, where they areheld by the cords 15 .until they are again unwound. A reverse movementof the .parts restores the conveyer to working position. If the partsare in the position indicated in dotted lines at I, the outer sectioncan be swung out, extending the carrier, the outer end of the section 9following the curve 3 Thecarrier would then be supported in positioninclining downward but little below the horizontal.

The dotted line 2 indicates the path that machine.

stated, receives power from the shaft of the band cutter. WVith thisbevel wheel meshes a wheel 26 mounted upon a shaft 27 supported in theframe work of the threshing A coupling shaft 28 unites the shaft 27 withthe shaft upon which is mounted the inner roll, 11, supporting theconveyer apron 10. The parts thus far described are connected togetherand employed when the conveyer O is situated on that side of the machinerepresented in Figs.

1, 2 and 3. Upon the opposite side of the machine there is arranged atrain of gearing 25, 26 and 27, corresponding, with the parts 25, 26 and27 already described. l Vhenever it is desired to change the later allyextending carrier or conveyer O to the position represented at IV, Fig.3, the coupling shaft 28 is disconnected, the conveyer frame is shiftedand the shaft 28 is then connected with the shaft 27, uniting it withthe shaft of the apron roll 11.

A clutch device, indicated as a whole by 35, is employed to connect, atwill, the shaft 24 with the devices from which it receives its power.

'What I claim is 1. The combination with a threshing-machine, of alongitudinally arranged straw feeder at the rear end thereof, atransversely arranged feeder pivoted to the side of the longitudinallyarranged feeder and comprising an outer and an inner section, the outersection being pivoted to swing downward with respect to the innersection but limited in its upward movement to a position of alin'ementwith respect to the inner section, an upstanding frame carried by theinner end of the outer section of the transverse feeder, a shaft mountedon the longitudinal feeder and above the same, a flexible draft devicesecured to the outer section, and adapted to pass in a straight linefrom the upper end of the said upstanding frame directly to the saidshaft uninterrupted by parts of the inner section located above thestraight line joining the axes of the pivotal connections of the innersection with the longitudinal feeder and the inner with the outersection, respectively, for all positions of adjustment of thetransversely arranged feeder, and means for drawing the draft devicesaround the shaft.
